Kindle is one of the easiest way to make money online if u ask me. Recipe books, even though they are freely available on the net, sells like 5 dollar whores and this is something we can take advantage of! If you create your own covers this method is totally free except for your time investment and my best month with this method netted me $2500... STEP 1: Find recipe niche and gather recipes from popular sites STEP 2: Run the recipes true http://phylix.com/products/spin/index.php and paste them into WORD STEP 3: Make your cover on photoshop or https://pixlr.com/ (free) STEP 4: Upload to Kindle, price @2.99 and make sure to put your book in good high traffic categories Now you will pass Amazon's screening process and they will approve your book. Occasionaly costumers will report your book as duplicate and it will be blocked but just keep uploading books and money will grow. This obviously works with other niches as well... Be smart and creative and you have yourself a nice recurring $$$ Disclaimer: Its been a little while since i did this, but it always worked!
